To find this behaviour annoying and martyr like.

She has mild learning difficulties and much of her behaviour I find very selfish, which I think is a combination of both the learning difficulties and her personality (I have an uncle who is very similar)

She always puts herself first, and will never go out of her way to do anything else for somebody unless it benefits her. Recently I have told her how upset I am by her selfish behaviour.

Her response to this has been acting so selfless, it actually comes across in my (probably unreasonable) opinion as acting like a martyr.

e.g. When she was sitting with the paper, I asked how long she would be. I would consider a typical answer "Don't worry, I'll only be 5 minutes" or something similar. Her response is "I haven't finished, but here, you can have it."

e.g. She was standing next to the bath in her towel (with the door open, don't ask me why!) It wasn't clear if she was about to get in, or had just gotten out, so I asked her. I would consider a typical answer "Sorry, I'm just about to get in, I'll be as quick as I can" or something similar. Her response is "I haven't had a bath yet, but you can go first."

I find this behaviour really annoying and martyr like.

When she says these things, it actually makes me feel bad and guilty, when I didn't intentionally do anything wrong. I am trying my best to get on with her, but she just makes me feel bad, as if I was taking advantage of her.

I don't think she is trying to upset me on purpose, actually I think she is trying to take on board what I said about her being selfish, and actually trying to make me happier. She is just going about it in a way that inadvertently upsets me.

I think she's trying and maybe you could just reply. No it's ok ill wait till your done, I just wasn't sure if you had finished. Not really sure why this is annoying you if you don't think it's malicious

Could it be that you may need to change how you ask things to clarify what you want so instead of how long will you be? Ask, when you have finished, can I have the paper after you? Small things can make all the difference when asking someone who may not quite understand the hidden meanings that we take for granted.

I will try that next time, it is possible that will make the difference.

If I was your sister, being asked about the paper while still reading it would make me feel pressured into finishing it quickly or handing it over, which is a small, insignificant pressure point, but pressure nonetheless.

If you then asked me if I was getting in / out of the bath, that would be another small pressure point. These pressure points would soon build up and I would start to resent you and feel protective of myself (i.e. selfish).

Maybe YOU have made her that way?

You could have waited ten minutes, half an hour, an hour even in the examples above and you would know if the paper/bath was free without hassling the poor woman.

But having said that, are you living with your sister? I think I'd find it hard to now live with my parents or sister and they'd probably get on my nerves, even though i get on fine living with my husband and children.

The way I would approach the paper/bath examples are. "I'll read that when you've finished." Or if it is her paper "Can I read that when you've finished." For the bath I'd say "I'll go in after you." That way they know you only want to go in once they have finished rather than wanting to go right now

Not really, especially not with the bath. It was 10:00 at night, and I needed to know if she was running a bath so I knew whether or not to put the hot water immersion heater on. It takes a good half hour to heat up, and just knowing whether I needed to turn it on or not would make a big difference.

I knew that there was enough hot water left for two showers, or one bath, so knowing what she was planning on doing made a big difference. I needed to know if she had already had her bath/ shower, so I could have a bath/ shower without turning on the immersion heater. As she had not, I needed to turn it on. It would have been helpful if she could have just answered the question rather than being obtuse.

Like I've said, I will definitely try this. But I have a suspicion that it is far more about her trying to force me to go first so she does't appear selfish, rather than a misunderstanding. I will try it though.
